Book excerpt: The delivery of cell-impenetrable therapeutic agents across biological barriers represents a challenging problem in the field of life science research and medicine. Many bacterial pathogens are inherently resistant to glycopeptide antibiotics such as vancomycin due to the antibiotic's relatively large size and mode of action, which requires actively growing cells. Recently, genetically-resistant vancomycin strains have emerged, adding to vancomycin's inefficaciousness against certain bacterial populations. The emergence and understanding of phenotypically and genetically resistant bacteria coupled to a declining pipeline of antibiotic development necessitates new strategies to combat bacterial infections. As part of a collaboration between the Wender and Cegelski labs, we have designed, synthesized and evaluated a novel vancomycin cell-penetrating peptide conjugate. We have shown that this new conjugate exhibits a unique mode of action compared to vancomycin, allowing it to be extremely effective against vancomycin-insensitive bacterial populations.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: My graduate studies have focused on the design, synthesis, and biological evaluation of novel probe and drug delivery technologies. This research has explored the development of new molecular transporter scaffolds with a focus on step economy and translational costs as well as evaluation of their uptake and delivery properties in cells and animals. Chapter 1 provides a historical context and overview of guanidinium-rich molecular transporter technology. Chapter 2 describes the development of a new family of guanidinium-rich oligocarbonate molecular transporter which are flexibly and efficiently assembled by a one-step oligomerization strategy. These novel oligocarbonate transporters were shown to exhibit excellent uptake properties both in cells and animal models. Chapter 3 is directed at the utility of an oligomerization approach to generate molecular transporters by the design, synthesis, and evaluation of new aphipathic co-oligomers for the delivery of siRNA, an oligonucleotide cargo of intense therapeutic interest. Amphipathic carbonate co-oligomers were prepared by an oligomerization strategy and demonstrated to effectively package, deliver, and release functional siRNA in cells. Chapter 4 describes the effects of a branched guanidinium array on the transport and delivery efficiency of releasable dendrimeric guanidinium-rich transporters. These transporters were synthesized and demonstrated to deliver and release a small molecule for turnover by its intracellular target enzyme by bioluminescence assays in cells and transgenic animal models. Chapter 5 describes the design, synthesis, and preliminary biological evaluation of lipidated molecular transporter derivatives of the immunosuppressant drug rapamycin for topical delivery.

Available in PDF, EPUB and Kindle. Book excerpt: This book features a special subsection of Nanomedicine, an application of nanotechnology to achieve breakthroughs in healthcare. It exploits the improved and often novel physical, chemical and biological properties of materials only existent at the nanometer scale. As a consequence of small scale, nanosystems in most cases are efficiently uptaken by cells and appear to act at the intracellular level. Nanotechnology has the potential to improve diagnosis, treatment and follow-up of diseases, and includes targeted drug delivery and regenerative medicine; it creates new tools and methods that impact significantly upon existing conservative practices. This volume is a collection of authoritative reviews. In the introductory section we define the field (intracellular delivery). Then, the fundamental routes of nanodelivery devices, cellular uptake, types of delivery devices, particularly in terms of localized cellular delivery, both for small drug molecules, macromolecular drugs and genes; at the academic and applied levels, are covered. The following section is dedicated to enhancing delivery via special targeting motifs followed by the introduction of different types of intracellular nanodelivery devices (e.g. a brief description of their chemistry) and ways of producing these different devices. Finally, we put special emphasis on particular disease states and on other biomedical applications, whilst diagnostic and sensing issues are also included. Intracellular delivery / therapy is a highly topical which will stir great interest. Intracellular delivery enables much more efficient drug delivery since the impact (on different organelles and sites) is intracellular as the drug is not supplied externally within the blood stream. There is great potential for targeted delivery with improved localized delivery and efficacy.

Book excerpt: In this book, a summary and update of the most important areas of CPP research are presented, whilst raising relevant questions for further development. The CPP sequences are presented and discussed throughout the book. The methods for testing CPP mechanisms are discussed in detail. Various approaches for the testing of endocytotic pathways of CPP uptake are also described. Different CPP uptake experiments are compared since it is becoming clear that it is often best to apply several methods in a complementary manner in order to most comprehensively evaluate CPP uptake mechanisms due to the complexity of these processes. A brief summary of functionality issues of CPPs, both in vitro and in vivo are discussed. Therapeutic potential of CPPs and commercial developments are discussed. The monograph is written for researchers and students in the field.

Available in PDF, EPUB and Kindle. Book excerpt: This third edition is a comprehensive and extended study about the best known approaches for preparing the main types of glycosides, covering the classic and more recent glycosylation reactions used for preparing simple and challenging glycosides currently used as potent antiviral and antineoplastic drugs, or fluorogenic substrates used for enzymatic detection in cell biology. Besides, this new edition provides more examples of the glycosidic methodologies followed for preparing complex glycoconjugates such as glycoproteins and glycosphingolipids and gangliosides used as adjuvants or as synthetic vaccines candidates. Also, additional mechanistic evidence is presented for better understanding of the glycosylation reaction, trying to identify the variables mainly depending on protecting and leaving groups, as well as catalyst and reaction condition which altogether directs the anomeric stereo control. A chapter on the glycoside hydrolysis is included in view of the increasing interest in the use of biomass as a natural and renewable source for obtaining important intermediates or products used in food or valuable materials. The author includes information in the characterization of glycosides section with the aim of giving additional tools for the structural assignment through NMR, X-Ray and mass spectra techniques.

Book excerpt: PREFACE The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture is involved in agricultural research and development and assists Member States of FAO and IAEA in improving strategies to ensure food security through the use of nuclear techniques and related biotechnologies, where such techniques have a valuable and often unique role. In particular, molecular diagnostic methods have rapidly evolved in the past twenty years, since the advent of the Polymerase Chain Reaction (PCR). They are used in a wide range of agricultural areas such as, improving soil and water management; producing better crop varieties; diagnosing plant and animal diseases; controlling insect pests and improving food quality and safety. The uses of nucleic acid-directed methods have increased significantly in the past five years and have made important contributions to disease control country programmes for improving national and international trade. These developments include the more routine use of PCR as a diagnostic tool in veterinary diagnostic laboratories. However, there are many problems associated with the transfer and particularly, the application of this technology. These include lack of consideration of: the establishment of quality-assured procedures, the required set-up of the laboratory and the proper training of staff. This can lead to a situation where results are not assured. This book gives a comprehensive account of the practical aspects of PCR and strong consideration is given to ensure its optimal use in a laboratory environment. This includes the setting-up of a PCR laboratory; Good Laboratory Practice and standardised of PCR protocols.
